In the Sand Village, the originally dusty climate has been greatly improved.

In the boundless desert, there are gradually more greenery, sporadic pastures and windbreakers gradually spread, and agricultural and animal husbandry bases of all sizes have also been laid out.

The big problem that plagues the Wind Kingdom now is that with the drastic changes in the overall environment, many natural and man-made disasters that did not have conditions in the past have also occurred.

The floods that were not long ago were just a relatively small impact. At present, the most shocking thing is the flooding of hares and mice. The foxes, wolves, jackals, martens, snakes, eagles, raccoons and other animals that have restrained these amazingly reproductive animals. Their population has grown too slowly and cannot keep up with demand at all.

The biological communities formed in the desert in the past cannot adapt to the current Wind Kingdom.

If a pair of mice during the breeding period does not have external interference and sufficient food, the mice and grandchildren will be born at will, and the number will increase by nearly 10,000 times in a year; a pair of adult wild cats will be very good to have five or six kittens a year, and one-third of them will not live to adulthood.

Most of the natural enemies of mice and hares are not very fast in reproduction.

As the problem of water shortage in the Wind Kingdom is solved, it becomes more livable. The first thing that benefits are these endless annoying creatures.

Conservatively estimated that at least one generation of people can only achieve a barely balanced biological chain in the country of Wind in nearly twenty years and will not cause harm.

What is most annoying is that most of these pest populations are built nests in the underground, which are difficult to kill. They also like to gnaw on the rhizomes of plants, making the land that has finally turned green and becomes desertified again.

It is obvious that the Sandun developed the Wind Kingdom not only needs to confront the natural environment, but also eliminate these uninvited guys.

In view of this, Sand Village had to mobilize a large number of people to concentrate on removing these harmful organisms every time.

Every time I attack, the killed rats and rabbits piled up, they could form a hill twenty or thirty meters high.

Unfortunately, these low-wisdom creatures do not understand what "Jingguan" means, and they will not be afraid of such strangulation.

The fact is that as grassland vegetation spreads with river water sources of all sizes, the number of these beasts grows faster than the speed of extermination.

It is extremely ironic that Temari, the leader of the largest organization security department of the Sakai Village, originally formed this extremely inflated people-friendly ninja army to maintain the public order of Sakai Village, Awaji Village and Naruto Village. Most of the low-level ninjas and apprentices under their command were to protect the villagers and eliminate evildoers. As a result, its main task now has become to catch mice and catch rabbits.

There was a big operation every now and then, a small killing mission, which never stopped.

In principle, the fundamental reason for the security department is to protect the safety of the Sand Village. Whether it is humans, beasts or natural disasters that pose a threat, they are within their scope of their handling.

In the past, the country of Wind often broke out in locust plagues due to severe droughts. The whole army was dispatched to eliminate pests and protect the few oasis left in the country of Wind from being gnawed.

From this perspective, catching rats and hares is really a matter of duty.

This is the reason, but which member of the security department is willing to do this?

It is not easy to enter the security department. If you are not strong enough and have not been honest enough, you will not be able to be trusted.

After passing five levels and killing six generals, he defeated many competitors. He entered the security department to become a promising ninja, rather than playing "hide and seek" with mice and hares.

As dusk approached, I personally took the lead in presiding over a large-scale cleanup Temari. I exhausted myself and brought a group of dry men back to the Sand Village. After the subordinates were disbanded, I ate something to replenish food and water. Later, when I arrived at a place, I made a rumbling sound, but I couldn’t see too many messy scenes. There were only factories with vast land and towering walls.

After passing through several doors, I came to an indoor square. Temari saw a giant machine like an iron-smelting blast furnace in the center. The pressure relief valve on the upper cover made a sound of steam overflowing, and the heat wave was discharged with the fans on the top and around, so that the interior was not too hot.

There are many machines around the machine whose purpose is invisible, working under the manipulation of a group of Sand Ninja wearing white clothes.

It seemed that everyone was very nervous, and they exchanged a few words from time to time, but the voice was not loud.

Temari slowly approached and came to a command cabin. She saw Miss Saye, who was commanding her busy men through the walkie-talkie from time to time, watching the operation of the huge machinery in front of her with great concern.

"Seeing that you are very busy, am I here at the wrong time? Otherwise, next time..."

Before Temari could finish her words, Miss Saye put down the microphone in her hand, pushed open the glass sealed door and walked out.

"You came just right. I have a plan. After I became a plan, it will be of great help to the village. But it is too slow to proceed step by step..."

"So, want to ask me for help?"

"It's cooperation!"

Even if she asked someone, Miss Sha Ye seemed unwilling to admit defeat.

"Everyone gets what you want, it's not that I have to ask you, but I just bring you with you for the sake of Daimaru..."

"All right……"

Temari knows the style of Miss Saye who is stubborn and doesn't mind too much.

"I don't know what your 'plan' is, can I explain it in simple and clear words? You know, I'm not a puppet master, it's too troublesome, I don't understand..."

Nowadays, the traditional ninja forces in Sand Village, except for a few larger factions, are mostly controlled by Gaara; the new forces in the rise of the puppet industry represented by Daimaru have almost collected all the middle and lower puppet masters, puppet apprentices, and "quasi-ninjas" with high IQs.

The rest, as long as you can see it slightly, were all caught by the seriously short of people.

If we only calculate ninjutsu, Temari's security department is the largest department in the Sand Village. Let's talk about whether it can be fought for the time being, and the influence is really the best.

Because of its people-friendly nature, it naturally has advantages that traditional ninjas and technical ninjas do not have.

In the entire ninja world, in the non-war period, there is no other second one that maintains such a large-scale standing department except the Sakai Village Security Department.

Most of the people who ask Temari for help are attracted by the fact that the police station has a large number of people and want to get a share of the pie.

Temari, who is full of confidence, usually refuses politely, while Miss Saya is different. She has taken over most of the traditional puppet master forces and is regarded as the "old-school noble" in the Hidden Village of Sakura. In addition, her friendly position with Daimaru is naturally the person on the table.

During several large-scale developments, it was precisely because of Miss Sha Ye's face that many people took the last bus at lightning speed and became related to Daimaru and would not be marginalized.

This meeting seems to be another "corrupt" old faction, cooperation or competition with emerging aristocrats?

In short, no one wants to be abandoned by the times, and even if they really can't keep up, they are trying to maintain the situation.

Next, Miss Saya took Temari to visit several of the main facilities here.

"That big guy is actually a 'energy furnace'. As long as the ratio of chakra and natural energy is maintained, there will be no danger! The real core is actually this..."

Following Miss Saye's pointing, Temari saw a big guy who was nearly three meters high and had two rooms.

The appearance looks very metallic, obviously a mechanical creation.

“What is it?”

Unlike a combat puppet, it is a precise instrument composed of rows of neat connecting rods and gears.

Temari is sure that it is not just Sasaki Village, but even the ninja world, I have never seen such a thing.

“Essentially, it’s a differential!”

Miss Sha Ye explained slowly,

"This kind of thing has also appeared in the ninja world before, but with the emergence of electronic computers, it was quickly eliminated..."

"It's a microcomputer? I know this..."

Temari nodded,

"Is this the same thing? It looks very different..."

"There are common aspects of working principles, but the latter is much more advanced than the former..."

"Then... what's the use of making such a thing?"

“There is a big difference…”

Miss Sha Ye smiled proudly,

"Those computers of large and small sizes built with transistors or electronic tubes are too so sophisticated and are tools for ordinary people who don't know ninjutsu. Ninjas are different..."

Next, Miss Saye explained the real role of this "differential machine" in front of her in a way that could barely be understood by Temari.

Generally speaking, the more precise the instrument is, the worse the stability and the easier it is to damage.

For ninjas with strong individual power and extraordinary abilities, that thing is still very convenient as a laboratory data storage and computing assistance.

However, the core strength of ninja lies in chakra.

Give up the extraordinary factor and use pure technological creations, it is still a bit of a bad idea for the ninja.

For mortals, those small microcomputers can make up for many of their shortcomings.

But for ninjas, this kind of "mechanical computer" is stupid, stupid, can withstand torture, is not easy to damage, and can leave room for extraordinary power.

for example……

"The village's ninjutsu development over the past decades is inseparable from a crane, magnetic escape, and puppet technique, but in fact, there is a vein that runs through the whole process, that is, use natural energy!"

"In the past, our thinking was either to create puppets that were stronger and could even use natural energy, or like Damaru, using puppet techniques and blood transcendence as a springboard to cultivate into the immortal mode. In fact, we must have the trump card to absorb natural energy and die with the enemy."

"Just like the 'righteous puppet', the fusion puppet is just an appearance, essentially a pile of elements to accommodate natural energy; other things, such as human puppet technique, are similar considerations, but no one has succeeded, only Daimaru stepped on the shoulders of his predecessors and cultivated into the immortal mode, and then fed back the pre-secret technique to perfect it..."

Miss Saya, who said a lot in one breath, paused and took a break, finally made Temari find a chance to speak:

"To put it simply, it is this 'differential machine' that can make up for your shortcomings in the field of puppet technology in the past?"

"Basically correct, but incomplete..."

Miss Sha Ye said vaguely,

"No matter what kind of thinking it is, absorbing natural energy, you must consider the qualifications and strength of the caster. The universality is too poor! It took Damaru a person only to succeed in sixty or seventy years, and the next lucky person will appear. I don't know when! So, just take a different approach and temporarily put aside the immortal mode, and don't think about creating an "immortal puppet" that even an apprentice can use! No matter how magical the natural energy is, it is also an energy... at least it can be used as energy, which is enough!"

As long as society develops to a certain extent, political entities will definitely realize that the amount of energy they can possess will largely determine the strength of a force.

It is really too difficult to use natural energy to achieve the immortal mode and practice secret techniques, but it is much easier to directly use it as a source of power.

For example, coal has various types and uses due to the differences in composition. Instead of hard work and hard to sort, making various secondary industrial products with coal chemical technology, and pouring them into boilers to burn, it is the easiest way to use it.

It's enough to pour out the cinder afterwards.

Just like the problem mentioned by Miss Sha Ye now, the threshold for efficient use of natural energy is too high, but the difficulty of converting it into a power source is much lower.

Of course, natural energy is not natural gas, oil and coal. If you want to make good use of it, you must have a certain foundation.

"You mean, your 'differential machine' can use natural energy?"

Miss Sha Ye waved her hand and explained more to an outsider like Shimaru, and it is probably difficult for her to understand it. It is better to be straightforward:

"This is a regulator that uses complex algorithms to converge the violent and incomparable natural energy to a stable output. The energy furnace over there is the collection device..."

The so-called "differential machine" actually plays the functions of transformers and voltage regulators. What is missing now is external review and actual operation experiments.

"The whole Sand Hidden Village, almost all the powerless groups are under your command. I need you to assign a group of officials to accept the experimental conditions. It will not affect your completion of tasks, but will bring a lot of help..."

"for example?"

Upon hearing this, Miss Sha Ye smiled slightly and took out a half-person-tall rifle-like weapon.

"Multifunctional magnetic ejection gun, the output energy is not strong enough at present, but it should be very suitable for your current tasks..."

The skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is a skeleton, a skeleton is

It is not very practical to deal with ninjas. Ordinary adults do not hit the key points and can only be beaten to minor injuries. However, killing rats and hares is enough, and it is undoubtedly much more convenient than throwing kuna and shuriken.

After taking the strange weapon and weighing it, it was quite heavy. As a test work, it was a bit bulky.

“Is this thing useful?”

The ninja world has hot weapons, from loading heavy artillery to portable pistols, although expensive, they are also rich and powerful.

Miss Sha Ye replied:

"Make a weapon, it's just convenient to test. The real purpose is not convenient to disclose..."
